Patent FR-2274449-A1 (FR)
Title: Hardening and drying unit for printing ink - uses ultra-violet radiation to dry single-or multi-colour printing from offset printing machine
IPC: H05B3/00
Filed: 1974-06-17
Abstract: The housing of the drying unit has two openings, through which the printed web (13) passes, moving vertically upwards. The housing incorporates a lamp unit (14) with a reflector (30) a high intensity ultra-violet light source (37) and a unit for the rotatable mounting of the lamp unit in the housing so as to move the reflector from one position where the ultra-violet radiation is directed onto the web to a second position where the beam is directed away from the web. An energy absorption chamber is joined to the lamp unit and receives the radiation whenever the reflector is in its second position. An air circulation unit directs an air stream around the reflector and the chamber and through an assembly which screens the radiating lamp from the flowing air.

Title: Monitor for indicator with follower control - has driving pulley connected to indicator tape
IPC: G01R17/06
Filed: 1974-08-23
Abstract: The indicator has a device to produce an error signal by comparing a position signal with an input signal and a driving motor controlled by the error signal, which turns a driving pulley. A monitor responds to an error lasting longer than the adjustment time. The driving pulley has fastened to it a lever loaded by a spring and keeping the indicator tape stretched. The lever has a locking ratchet which engages with a fixed gear when the tension of the indicator tape is reduced in relation to the tension of the spring, thereby preventing the driving pulley from rotating.

Title: Mixed barium-strontium-calcium oxide cathode coating material - contg. much less barium and less strontium oxide, reducing volatility
IPC: H01J1/142
Filed: 1975-01-23
Abstract: The cathode oxide coating material contains 1-20 mole % BaO, 30-50 mole % SrO and 40-65 mole % CaO. The coated anodes are used e.g. in amplifier and transmitting tubes. Volatilisation of the oxide coating material is greatly reduced, whilst a high emissivity is retained, i.e. a low work function is ensured, by the use of more CaO, much less BaO and less SrO than usual. The volatility is 0.08-0.2 units at 1050K, i.e. 5-12 times less than usual, whilst the work function remains at 1.50-1.65 eV. The drop in emission is only 20-35% in 5000 h operation (cf. ca 50% for the usual material contg. equimolar amts. of BaO and SrO and up to 13 mole % CaO).

Title: Single crystals of zirconium or hafnium dioxides - stabilised with yttria to obtain high microhardness for jewellery or optics
Inventor: ALEXANDROV V I
IPC: C30B11/00
Filed: 1975-03-11
Abstract: Single crystals based on stabilised zirconium dioxide or hafnium dioxide, contg. yttrium oxide as teh stabiliser, the novelty being the use of the constituents in the molar % ratio of: >90 to 95% ZrO2 or HfO2, and 10 to 5% Y2O3. The single crystals may also contain 0.01-5 wt % of the oxides of the transition metals and/or the rare earths. Conventional crystals of ZrO2 or HfO2 stabilised with Y2O3 have high optical quality but a relatively low microhardness of 13000-14000 MN/m2 which restricts their use in jewellery, optics and laser elements. The invention permits the mfr. of single crystals with high microhardness, e.g. above 18000 MN/m2.

Patent FR-2312658-A1 (FR)
Title: Automatic advance for diesel engine injection pump - using centrifugal governor to control oil flow to hydraulic piston
IPC: F02D1/18
Filed: 1975-05-28
Abstract: The hollow shaft (4) rotates in the bearings and is driven from the diesel engine through the gear wheel (5). The drive to the fuel pump shaft is transmitted through the helicoidal splines by the piston (12) which in turn is driven by the parallel splines from the shaft (4). Oil supplied by the engine pump flows into the annulus (17) and out through a radial hole in the inner piston (8). As engine speed increases, governor weights cause the piston (8) to move to the left shutting off the oil outlet so that the oil pressure rises. This causes the piston (12) to move to the right, rotating a shaft and advancing the operation of the fuel injection pump.

Title: Rack frame with adjustable rails - has rail and fittings offset from centre line to allow inversion (BR 18.10.77)
Inventor: LUNEAU GERARD
IPC: A47B57/48
Filed: 1976-03-08
Abstract: The frame is particularly for bottle racks, having a number of pairs of columns joined by rails, the latter having fittings on the ends by which they are secured to holes at regular intervals in the columns. The two fittings (7, 8) on each rail (3) are symmetrical about an axis perpendicular to the plane of rail and equidistant from the columns. The centre line (X1, X'1) of the rail is offset from that of the fittings by an amount equal to one quarter of the pitch of the holes (5, 6) in the columns. The Interval between the holes in the fittings is the same as the column hole pitch. Thus each rail can be mounted either way up, increasing the number of different relative positions in which they can be mounted.

Title: Rotary shaft seal with floating seal ring - is self balancing to maintain constant escape flow through small radial gap
IPC: F16J15/34
Filed: 1976-03-16
Abstract: The rotating shaft seal assembly separates two areas of different air pressures. A seal ring (14) has equally spaced axial holes (30) which are interconnected by an axial groove (32) on the low pressure side (P2). A fixed ring (16) with a small radial gap at the seal housing (10) restricts the air flow to the low pressure area. The seal ring (14) is able to float axially within the limits allowed by the location element (26). When pressure variations occur, the resulting axial movement of seal ring (14) is such that the designed air escape flow is maintained. A self balancing rotating air seal is thus obtained.

Filed: 1976-04-01
Abstract: The riveting system is entirely hydropneumatic and consists of two cylinders joined end to end and having a common piston rod and two pistons which reciprocate inside the two cylinders. The controls enable the pistons to effect a push and pull motion on the rivet. The hydraulic system is equipped with relief valves, including a balance valve which controls the pressures to a predetermined level. The valves are spring-loaded to ensure their correct operation. When the rivet is finally in position the tail end of the rivet is fractured.

Title: Winding mechanism for vehicle windows - with two crossed oscillating arms linked to window and hinged together
Inventor: KLUTING BERND
IPC: E05F11/44
Filed: 1976-04-15
Abstract: Winder for vehicle windows has two crossed oscillating arms linked to the window at one end and hinged together. One acts as the lifting arm (11) and is activated by a control mechanism, while the other is the guiding arm (12) and consists of two parts (20, 21). The hinge is formed by a circular hole drilled in one arm, the lifting arm, and a swivel-pin which rotates inside this hole and is placed between the two parts of the guilding arm. The swivel-pin is a ring of the same thickness as the arm (11) in which the hole is drilled. the two parts of the guiding arm are joined toether and are able to rotate by resting on the two flat faces of this ring. This type of winder is less expensive both to manufacture and instal, primarily because its components are simplified.

Title: A=D encoder with preset coding plate - uses variable gain amplifier circuit which produces constant signal with controlled variable phase shift
Inventor: BERARD HENRI
IPC: H04N7/24
Filed: 1977-01-20
Abstract: The method is for adapting an analogue signal to a digital code for use in a coder functioning by coding amplitude samples of a signal. The coder has a given coding range. In front of the coder is a controlled variable gain amplifier circuit. This circuit can produce a constant continuous signal with controller variable value of phase shift. A range of amplitude variation of a test signal having amplitude characteristics similar to that of the analogue signal is determined. Resulting from the amplitude variations, a control of gain and a control of the shift of the constant signal from the amplifier circuit is determined. The control of gain and shift corresponds respectively to a value of gain and a value of signal phase shift such that the range of variation of the test signal coincides approximately with the code range of the coder. The analogue signal is applied to the amplication circuit controlled by the control thus determined and delivers a signal designed for the coder.
